More Information
Summary:The invention provides an antioxidant, a preparation process of a high-temperature antioxidant flexible graphite plate, and the high-temperature antioxidant flexible graphite plate. The preparation process comprises the following steps that S1, making expandable graphite particles expanded and rolled into a flexible graphite plate at high temperature; S2, dipping the flexible graphite plate into the antioxidant provided by the technical scheme, and standing in a vacuum device for 2 hours; and S3, taking out the flexible graphite plate subjected to antioxidant dipping treatment, putting the flexible graphite plate into a drying oven at 60 DEG C for baking for a certain period of time, and taking out the plate to prepare the high-temperature oxidation-resistant flexible graphite plate. According to the technical scheme, the thermal weight loss of the prepared high-temperature oxidation-resistant flexible graphite plate in a high-temperature oxygen-enriched environment of 800 DEG C for 1.5 hours is less than 30%
